**Problems Fixed:**
- Remove invalid 'http-request set-status' directive (not supported in HAProxy 3.0.11)
- Replace with proper blocked backend using 'http-request return'
- Add blocked backend template for serving blocked page with 403 status
**Changes Made:**
- Create hap_blocked_backend.tpl template for blocked IPs
- Update hap_listener.tpl to use blocked-backend instead of invalid status setting
- Modify haproxy_manager.py to include blocked backend in config generation
- Add blocked_ip_page.html copying to HAProxy directory during config generation
**Technical Details:**
- HAProxy 3.0.11 doesn't support 'http-request set-status' directive
- Use 'http-request return status 403 content-type text/html file' instead
- Blocked IPs now get proper 403 status with custom HTML page
- Configuration validation should now pass without errors
**Testing:**
- HAProxy configuration validation should succeed
- Blocked IPs should see custom page with 403 status
- All existing functionality maintained
